CONCRETE BUILDING CONSTRGTION.

Application led September 11, 1922. Serial No. 587,595.4

Y 10 all whom t may concern.'

Be it known that LYCHAnLns GBRIEN, subject of the King `of Great Britain and Ireland, residing at 1,06 Australia Street, Newtown7 nearr Sydney, New South l/Vales, Australia, havcinvented new and useful linprovernents in and Relating' to Concrete Building,` Construction, of which the following; is a specification.

ln carrying outmy invention l provide outer form pla-tes mounted on vertical standards, and collapsible sheet metal cores which are adapted to be aligned within the wall form plates'and to be securedthereto by mea-ns of metal spacing pieces. The cores are ofsuch a form that they overlap each other and have aininor portion .of their length of reduced width solthat when the mould is filled with concrete a vertice. strengthening vrib is formed in the `cavity faces of the wally shell. This form of core gives a wall section with maximum width of cavity between wallties and minimum width of cavity the vertical lines where wall ties occur, thus permitting a much lighter construction otwall shell without reducing` its strength.

e T0 facilitate the supply of concrete to the `mould the core boXes are surmounted with Fig; l is a plan of a fragmentiof foundation wall plates showing the means by which the plates .are connected together;

a similarv Fig. 8 is a vertical section of a fragment of a wall mould supported by the foundation;

Fig. 9 is a plan of a wall mould showing spacingr members and reinforcements;

Fig. l0 is a side elevation ofthe means for securing' wall form plates to the standards.

Fig. ll is a plan of the same;

l? 1la is a sectional detail of one of the said vertical angle bars.

Fig. l2 is a sectional elevation of the upper portion of wall mould, bow and rail; and

Fig. i3 is a plan showing the means for positioning the inner ends of one core bor` within an adjacentl box.

Foundation plates Q0, which are rein` forcedwith angle iron bars 2l, are detachably connected to each other in vertical alignment by means of bolts 22 which pass through twisted locking lingers 23-24 secured to the plates. llt'the corners are positioned external and internal brackets 25-26 holed at 2T. Through the holes 27 vertical aligning rods 28 are passed. These rods are retained in position in the brackets by leaf springs 29 which are attached to the brackets and project slightly into the holes 27.

After the concrete foundation is coinpleted. and the foundation platesremoved vertical standards 30, 3l, formed from 'l' and angle iron bars. to whichwall form platesB are to be attached are positioned over the foundation. lThe lower ends 33, 34 of the standards, spaced by bolts 35, contact with the sides of the concrete foundation and the bolts 35 may rest on the foundation or pass therethrough. If desired, the standards 30 and 3l may be bolted to the foundation plates before or after the foundation is completed.

The upper ends of the standards are spaced by means ot bolts 36 and are prov led with clips 37 to ensure the attachment of horizontal angle iron'bracing SSL Horibent at their ends ll5 and make a wedge fit in tapering lugs 4G secured to the standards 30, 3l.

.l\/lou1 it ed in thefupper ends ofthe Vstandards 250, 3l are loose links t7 (Figs. 7 and l2) which are adapted tojretain .in position bows 48, bolts or bosses 4:9 on the bows pre- `venting further downward movement orf thev are yreducediin width at the ends 55 so that.

they maybe gripped by the tree `ends ol shorter and narrower core pieces 156 which are bent to overlap each other at the'inner ends". and are slip riveted at 57, the stud oit each rivet being adapted to travel in an .clined slot in the adjacent member 56. The pairs of' core pieces 5G are connected to each other by means of relatively narrow core boxes comprising slidingplates 58 which are provided with studs 59 to engage in inclined slots 6() in the pieces.

` Ondrawing the plates 5S with the studs 59 upwards inthe slots G0 the pairso'tl plates '56 are drawn towards each `other and. are thus" `freed Atrom the Vreduced ends olf the cores Atfthesame time the studs :'37 travel upwardly7 in" the slots in the inembers 5G,'dravving the individual members ol each pair towards eachother, and permit the cores 54 and:members56 and 58 to be 'removed; Reverse "movement of theV plates 58, as'shown in Figs. 5 and 6 locks the cores in position." y

' The widerfree end' of thecore 6e is telescopedfinto; or slipped within the open end .of the core in the saine wall cavity as shown t einig. is.

.iron Stia llaced'across y'the core pieces 56 is a wall tie 61,v kinked atjGQf. The tie rods are adapted 'to be wired through holes or notches 62A, 8, inthe outer and inner wall Aplates f and secured temporarily thereto, thus preventing bulging of the lorm plates under pressure. `Horizontal rods` or wires 63 may aljsioQbev inserted within the mould yspace toy reinforce the wall,y ,v y 4 "lwrllo prevent the admission of'conerete into the"fclore boxes Aduring the mould Vfilling cpne'rationand to direct,anddistribute the liow finto the mould, the core boxes 5e are pro-- 'jtecfted by sheet metalrcaps 66 (Fig. 1.2).
